Sistem pencernaan Presentation Transcript

  • 1. ANATOMI DAN FISIOLOGIANATOMI DAN FISIOLOGI SISTEM PENGHADAMANSISTEM PENGHADAMAN
  • 2. FUNCTIONS OF THE DIGESTIVE SYSTEM 1. Take in food 2. Break down the food 3. Absorb digested molecules 4. Provide nutrients 5. Eliminate wastes
  • 3. The Digestive System
  • 4. ANATOMY ANDANATOMY AND HISTOLOGY OF THEHISTOLOGY OF THE DIGESTIVE SYSTEMDIGESTIVE SYSTEM
  • 5. Digestive Tract Histology 1. Mucosa 2. Submucosa 3. Muscularis 4. Serosa (adventitia)
  • 6. Oral Cavity 1. Lips and Cheek 2. Tongue 3. 32 teeths 4. Palate and Tonsils 5. Salivary Glands
  • 7. Oral Cavity 1. Bibir dan pipi - mengunyah dan bercakap 2. Lidah - bercakap, merasa, mengunyah, menelan 3. 32 gigi - mengerat, melumat/menghancur - crown, neck and root 4. Lelangit - keras dan lembut 5. Salivary Glands - menghasilkan serous dan mocous 3 glands - 1. Parotid, 2. Submandibular, 3. Sublingual glands
  • 8. Salivary Glands
  • 9. Pharynx (tekak) 1. Nasopharynx 2. Oropharynx 3. Laryngopharynx Esophagus
  • 10. Esophagus 1. Salur memanjang dari pharynx ke stomach melalui diaphragm 2. Ukuran panjangnya 25 sm 3. Esophageal sphincters mengantar makanan keluar dan masuk esophagus 4. Cardiac sphincter - lower esophageal sphincter 5. Mucous glands - mucus
  • 11. EsophagusEsophagus StomachStomach Heart
  • 12. Stomach 1. Stomach - cardiac region and pyloric region 2. The wall of stomach 3 layers; i. longitudinal ii. circular iii. oblique 3. Gastric glands produce; i. mucus ii. hydrocloric acid iii. pepsin iv. gastrin v. intrinsic factor
  • 13. StomachStomach
  • 14. StomachStomach
  • 15. Small Intestine Small intestine - 3 parts: i. duodenum ii. jejunum iii. ileum Intestinal Lining - circular folds, villi dan microvilli Goblet cells & duodenal glands - mucus
  • 16. Small Intestine
  • 17. DuodenumDuodenum
  • 18. Liver 1. Liver menerima darah daripada: i. hepatic artery ii. Hepatic portal vein 2. Liver produces ‘bile’. Bile leaves lever - hepatic duct system. 3. Liver devided into lobules - portal triads 4. Portal triads: I. hepatic portal vein ii. hepatic artery iii. hepatic duct
  • 19. Liver
  • 20. Pancreas 1. Pancreas adalah kelenjar endokrine dan exorine. 2. Tugasnya mengawal tahap nutrein darah 3. Exocrine menghasilkan; i. bicarbonate ions ii. digestive enzymes
  • 21. Liver, gallbladder, Pancreas and Duct System
  • 22. Liver, gallbladder, Pancreas and Duct System
  • 23. Liver Histology
  • 24. Anatomy and Histology of the Pancreas
  • 25. Large Intestine 1. Colon terdiri daripada; i. Ascending, ii. tranverse iii. descending iv. Sigmoid portions 2. Mengandungi mucus - crypts 3. Rectum adalah saluran lurus - anal canal 4. Cecum and appendix - blind sacs 5. Cecum - junction of small and large intestines.
  • 26. Large Intestine
  • 27. Peritoneum and Mesenteries
  • 28. MOVEMENTS ANDMOVEMENTS AND SECRETIONS INSECRETIONS IN THE DIGESTIVETHE DIGESTIVE SYSTEMSYSTEM
  • 29. Sistem Penghadaman 1. Sistem Penghadaman di atur oleh: i. neural ii. hormonal mechanisms 2. Intramural plexuses bertanggungjawab kepada ‘local reflexes’
  • 30. Oral Cavity, Pharynx and Esophagus 1. Amylase (saliva) mula penghadaman. 2. Mucin menghasilkan pelincir 3. Gigi - menghancurkan makanan 4. Voluntary phase: Bolus akan ditolak oleh lidah ke pharynx
  • 31. Oral Cavity, Pharynx and Esophagus 5. Pharyngeal phase: i. soft plate close nasopharynx ii. epiglottis close - larynx iii. pharyngeal muscles move the bolus to the esophagus iv. Peritalsis ( a wave of constriction) moves the food down to the stomach
  • 32. 3 fasa Menelan (1)
  • 33. 3 fasa Menelan (2)
  • 34. 3 fasa Menelan (3)
  • 35. Stomach 1. Secretion of the Stomach i. mucus protect the stomach lining ii. hydrocloric acid kills microorganisms & activates pepsin iii. pepsin starts protein digestion iv. intrinsic factor aids (vitamin B12 ) absorption v. Gastrin helps regulate stomach secretion and movements.
  • 36. Stomach
  • 37. Stomach
  • 38. Stomach
  • 39. Stomach 2. Regulation of stomach Secretion i. Cephalis phase - sight, taste, smell ….. ii. Gastrin - stomach secretion iii. Gastric phase - promotes secretion iv. intrinsic factor aids (vitamin B12 ) absorption v. Gastrin helps regulate stomach secretion and movements. vi. Intestinal phase - acidic chyme
  • 40. 3 Fasa Perembesan Gastrik
  • 41. 3 Fasa Perembesan Gastrik
  • 42. 3 Fasa Perembesan Gastrik
  • 43. Stomach 3. Movement in the stomach i. Mixing wave mix the stomach contents with the stomach secretion - chyme ii. Peritalsis wave moves the chyme to the duodenum
  • 44. Small Intestine 1. Secretions of the small intestine i. Mucus protects: - digestive enzymes - stomach acid ii. Chemical or tactile irritation
  • 45. Small Intestine 2. Movement in the small intestine i. Segmental contraction occur - short distance - mix intestinal secretion ii. Peritalsis contraction occur - length distance - propel chyme 3. Most absorption occurs in the duodenum and jejunum
  • 46. Liver 1. Liver produces; i. ‘bile’ - emulsify fats ii. stores and processes nutrients iii. produces new molecules iv. detoxifies molecules v. produces blood proteins
  • 47. Kawalan Rembesan ‘Bile’
  • 48. Pancreas 1. Pancreas produces; i. bicarbonate ions ii. digestive enzymes 2. Acidic chyme - a watery bicarbonate solution 3. Fatty acids and amino acids (duodenum) - pancreatic enzymes
  • 49. Pancreas
  • 50. Large Intestine 1. Functions: i. feces production ii. water absorption 2. Much longer to move 3. In the colon, chyme is converted to feces 4. Mass movements occur 3/4 times/day 5. Defecation - elimination of feces
  • 51. DIGESTION, ABSORPTIONDIGESTION, ABSORPTION AND TRANSPORTAND TRANSPORT
  • 52. 1. Chemical breakdown of organic molecules into their component parts 2. After digest; - some diffuse through the intestinal wall - transported across the intestinal wall Digestion, Absorption and Transport
  • 53. Carbohydrates 1. Polysaccharides (split) to disaccharides by salivary and pancreatic amylases 2. Disaccharides (breakdown) to monosaccharides by disaccharides - surface of intestinal epithelium 3. Monosaccharides absorbed - blood, carried by portal veins to liver 4. Glucose - carried and enter into the cells by facilited diffusion. 5. Insulin increases the rate of glucose transport
